Nearly one year ago at CES 2011, Dell introduced the Streak 7 Android tablet. The 7-inch tab was an oversized brother to the older Streak 5 tabletphone. Much like the Streak 5, the Streak 7 featured a mobile radio, making it a versatile tablet. Plus, costing only $200 on-contract at T-Mobile, the Streak 7 was actually affordable. But it doesn’t matter anymore. Dell just killed its last Android tablet dead.
