4. Dell Mini 5 (Streak)
Dell is working on a "family of tablets" the first of which will be its Android Mini 5 tablet. This unit's 5-inch display is more pocket-friendly than most upcoming tablets, but bigger than most smartphones (yes, it can make calls).

5. Lenovo IdeaPad U1

6. Microsoft Courier
One upcoming tablet that may match Apple is the mysterious Microsoft Courier, a folding dual-screen device that's more of a pen and touch-controlled digital journal/eReader affair.
Rumoured specs... OS: Based on the Windows CE 6 kernel (also the basis for Windows Phone 7 smartphones and the Zune HD) Key specs: Twin multitouch screens capable of pen input, nVidia Tegra 2 processors Other features: Pen-centric interface with handwriting recognition
Size and weight: Less than 1 inch thick, About 5 by 7 by less than 1 inch (height by width by thickness) when closed; weight will be a little over 1 pound

8. Netbook Tablets
If you like the idea of flicking through Web pages or e-books by touch, but you don't want to give up your physical keyboard, a netbook equipped with a swivelling screen could be a good compromise choice. Over the next few months, several new "netvertibles" (hmm, wonder if this means that the Internet's backbone will soon become known as the "netvertebrate"?) will emerge, including the Lenovo IdeaPad S10-3T (available now), Viliv S10 Blade, Asus Eee PC T101MT and the Gigabyte Touch Note T1000P. Each will have a 10.1-inch multitouch display, run Windows 7, and cost around $500 bucks. That's cheaper than standard 12.1-inch convertibles such as the multitouch-capable HP TouchSmart tm2t and Lenovo ThinkPad X201T.
9. ExoPC Slate
The ExoPC Slate was scheduled to arrive at the end of March, but ExoPC recently told Engadget that it has postponed the launch to June or July.

10. Archos 9 PCtablet
On paper, the Archos 9 looks impressive. Specs include a 60GB hard disk, Windows 7, a front-facing Webcam, Flash support, and a price of $549. But its 8.9-inch display is resistive and lacks multitouch, and the company appears not to have made Windows 7 more finger-friendly. Archos also announced the Archos 8 Home Tablet, essentially an touchscreen photo frame that runs Android.
OS: Windows 7 Starter Edition
Key specs: 8.9-inch LED-backlit resistive single-touch display (1024 by 600 pixels), 1.2GHz Intel Atom Z510 CPU, 1GB of DDR2 SDRAM, 60GB hard-disk drive, Intel GMA 500 graphics, 802.11b/g Wi-Fi, Bluetooth

11. ICD Ultra
Innovative Converged Devices' 7-inch Ultra tablet is yet another pairing of Tegra 2 and Android, but ICD's offering will emphasise affordability. The Ultra's big brother (the 15.6-inch ICD Vega) is headed to T-Mobile before the end of the year.
OS: Android 2.0
Key specs: 7-inch resistive single-touch display (1024 by 600 pixels or 800 by 480 pixels, capacitive versions are expected as well), 1GHz nVidia Tegra 2 (TegraT20) CPU, 256MB of RAM and 512MB of ROM, 4GB of internal flash memory (nonremovable), 802.11b/g Wi-Fi, Bluetooth, 3G option

Due: By June 2010
Price: Expected to start at $250, without carrier subsidies
12. Axiotron Modbook Pro
Ask Andreas Haas, the former head of Apple's Newton group, what he thinks of the iPad, and he'll tell you that "it's not a tablet; it's an extension of the iPod Touch." His company, Axiotron, is developing the Modbook Pro, a touch-enabled version of the pen-based, professionally finished Mac tablets that the business creates by converting MacBook laptops. Today you can buy pen-only Modbooks ready-made, or you can send your own MacBook to Axiotron, and the company will transform it into a Modbook for $700. The touch-capable Modbook Pro is should appear later this year, and it will probably cost quite a bit more than that.
13. MSI Tegra 2 Tablet
MSI is best known for netbooks these days, so it's no surprise that the company plans to produce an as-yet-unnamed tablet. The prototype Android "mPad" shown at CES had a 10-inch touchscreen, a Tegra 2 processor, HD Flash support, and an HDMI output. The finished tablet will probably cost around $500 and may arrive later this year. No doubt we'll learn more at the Computex Taipei Expo in June. Image credit and more information: DigiTimes.

Key specs: 10-inch touchscreen, nVidia Tegra 2 graphics and dual-core ARM Cortex-A9 CPU, 3G, Wi-Fi

Due: Possibly second half of 2010
Price: Expected to be around $500
14. Asus Eee Pad
This Tegra 2 tablet snapped at nVidia's CES booth isn't the sexiest prototype we've ever seen, but Asus has promised to launch a "killer product" in June. We should learn more come Computex time.
OS: Likely to be either Android or Chrome OS
Key specs: Likely to have nVidia Tegra 2 graphics and dual-core ARM Cortex-A9 CPU
Other features: 3G, Wi-Fi
Size and weight: Unknown
Due: Expected in the second half of 2010
Price: Expected to be around $500 (unconfirmed by Asus)
15. Camangi WebStation
Bad reviews: Complaints of slow performance, video playback issues, and sluggish single-touch response seem to have tarnished early hopes for the WebStation, a 7-inch Android 1.5 device designed primarily to run Web apps. For the $275 it costs, you're probably better off looking at the upcoming 7-inch ICD Ultra.
OS: Android 1.5
Key specs: 7-inch resistive single-touch display (800-by-480 pixels), 624MHz Marvell PXA303 CPU, 128MB of RAM, 256MB of ROM, 802.11b/g Wi-Fi, GPS

16. Freescale Smartbook Tablet Reference Design
Freescale makes the chips that most e-book readers (including the Kindle) use. The company has created a reference design for PC makers for low-cost $200 tablet PCs. The outline uses its ARM-based i.MX51 chip and includes a 7-inch tablet that can be docked with a keyboard base similar to Lenovo's IdeaPad U1.
OS: Chrome OS, Android, or Debian Linux with custom browser interface
Key specs: 7-inch resistive single-touch display (1024 by 600 pixels), Freescale i.MX515 (includes 800MHz ARM Cortex-A8 CPU and 720p video decoding), 512MB of RAM, 4GB to 64GB of internal storage, 802.11n Wi-Fi, Bluetooth, GPS, optional 3G

17. Apple iPad
What more is there to say? The iPad is a pleasure to use (despite some missing features), it hit stores on 3 April, and Apple's iBooks pricing may match Amazon's. Here are the specs.
OS: iPhone OS 3.2 Key specs: 9.7-inch multitouch display (1024 by 768 pixels) with IPS (in-plane switching, for better colour reproduction and a wider range of viewing angles), 1GHz Apple A4 system-on-a-chip with PowerVR SGX graphics, 802.11n Wi-Fi, 3G option
